Porter-Cable C2006 Compressor

[rhelmore]

My Porter-Cable C2006 compressor is less that 2 years old. Practically never been used. Less than 50 brads ever shot. I did complete the break-in when purchased as described in manual. Now that I am ready to use it, I hear air escaping from under the motor shroud. I removed the shroud to find air escaping from a hole on top of the cylinder head. I mean a hole that is manufactured into the cylinder head, not a defect in the head. I just don't know what this hole is for or what to call it. This is a fairly large amount of air escaping, not just a whisper. I have attached a picture of the cylinder head that I found on this website. Can someone please tell me what may be the problem?

Thanks.

Hey rhelmore,
The hole actually doesn't go all the way thu the head and has no real function..[its a dead end ]..The air escaping is probably coming from a bad tube seal..item # 104..part # CAC-1212..be sure and check the tube for damage also... most of the time its just a bad tube seal..they go bad from heat build up..and check the valve plate..a valve may be broken and causing the heat.. *since your air compressor is fairly new and hardly used the repair should be minor..*
Hope this is helpful..

I'm having the same problem, looking at the picture, the "hole" or indention has a tiny pin hole at the bottom that does go all the way through, I was thinking that it was suppose to go there, but after reading this I think not. Other than the mounting holes for the screws, it should have any "through" holes on the cover (CAC1196) right? Please advise.

Hey,
I am holding two of these in my paws right now..[used] I will be danged if one has a small pin hole and the other doesn't..I have never really had to change the the head before..so im not sure if the pin hole is deliberate [doesn't make sense..] or not..so the pin hole could be the cause of the problem...or it could be the difference between the types..hmnn..
I will check with the factory techs and see whats up..!

cmoorejack,

That is the exact same problem I am having with my Dewalt compressor. I can't see a pin hole but air is sometimes leaking out of the same hole that rhelmore referenced.

Do porter cable and dewalt use the same parts for the compressor? Mine is also around 2 years old and has been lightly used.

Hey Buckeye96
I am still waiting to hear back from Dewalt..I don't think there should be a pin hole and it may be a condition or result of other parts wearing out or getting too hot..in the case of not filling past 50 lbs..the cylinder/piston is more likely the problem..you will need to inspect for wear ..[any grooves in the cylinder or a broken lip seal on the piston] also that darn tube seal..since the cylinder head is readily available as a part replacement it may also be a concern..dewalt and porter cable are the same company now and they do use similar parts but is best to order the exact replacement part for your specific brand, model, and type..just in case

Cmoorejack,

Sorry i wasn't clear. It will pump all the way up but after 50psi it starts hissing air. I know it is coming out of the hole we referenced before (stuff something in there and the hissing stops). The other confusing part is that it isn't all the time. Sometimes it won't leak and other times it will.

I assume I just need to replace the head. What else should I replace while I am in there? Gaskets and such?

thanks for all your help

Hey buckeye96,
upon inspection replace whatever looks damaged or worn..
I would pay close attention to the valve plate assy and tube seal..
Happy repairing...!

I have the same problem. What's the deal? My guy told me that there was a batch of bad ones from the manufactuer and repaired it free of charge. I just complained a lot. try that. It's wierd that they would make it so hard for us to fix. Quirrks like that in the system really bug me.

good luck. and read your manual.. there's tips about how to get free/discounted repairs! It's all how you present yourself

peace

To finish up my story. I got the parts from eReplacement parts. It was a pin hole in the cylinder head. Put everything back together and the compressor ran well and filled the tank. I put the black box into the cradle and turned it on again to make sure it was okay. It ran fine for 10 seconds then I heard the fan starting to come loose, it made a 'pop' sound and smoke started coming from the black box. I unplugged it and clipped the power cord.

I found a new Hitachi EC119SA for clearance at Lowe's for $142. It isn't oil free or as light as the Dewalt but it is a lot more powerful and hopefully will last a lot longer than 2 years.

Try inspecting the check valve. Unplug and drain the unit of air. Remove the clamp and hose at the valve and try to draw air in with your mouth from the valve inlet. If you can, the valve is not working properly and tank air will leak back out if the pinhole in the head which is an atmospheric vent. To remove the valve use a 7/8ths deep socket and get your wife to hang onto the tank. Be sure not get any thread sealant residue or paint, or anything into the tank. Clean the threads with a clean fingertip. The new valve has a rubbery thread sealant. Tighten it all up and put a new clamp on the hose. Perform run in procedure as per manual.
